Configuration and calibration of the IRT 30 thermostat
You can switch the slow temperature rise on or off as follows:
1. Simultaneously press the INSERT, REMOVE and MENU key,
and release them.
2. Press the INSERT key twice again an hold it. On the display,
SLO or FASt appears.
3. Turn the program knob, while holding the INSERT key, until
the desired PID number appears in the display.
4. Release the INSERT key.
4. Reset the thermostat.
You can switch off the thermostat and switch it on again (reset).
This causes the thermostat to run the start and test program
again (refer to paragraph 5.2).
You can reset the thermostat as follows:
1. Simultaneously press the MENU, INSERT and REMOVE key,
and release them.
2. Again press the INSERT key three times and hold it. On the
display, tESt appears.
3. Release the INSERT key.
8.2 Calibration
Although the sensors of the IRT 30 thermostat are of high-
quality, some irregularities can not be avoided in the long term.
You can recalibrate the sensors then. Only recalibrate the sensors
when the measurement deviation becomes clearly evident and
irritating.
Incorrect calibration may have serious consequences to the
operation of the thermostat. Preferably, let the installer
recalibrate the thermostat during a service visit.
